You're stranded on an unknown planet, the home of numerous hostile creatures.
Shoot anything that moves, it's all against one.
One very well armed marine, that is..
I'd recommend choosing the Story Mode option.
Use the WASD keys to move around.
Hit R to reload your weapon.
Some creatures drop weapons and powerups (health and a 'timestop').
I'd recommend playing Story Mode.
